Answers covalent bond
A bond formed by the charge between a hydrogen atom (Inside
of a water molecule) and another atom (Or molecule) Correct
Answers hydrogen bond
A bond where electrons are shared equally Correct Answers
nonpolar Covalent Bond
A bond where electrons are shared, but one atom has a better
"grip" on the electron, making it lopsided. Correct Answers
